Tap water has never been a problem, and distilled water will support contaminates if it is not regularly cleaned anyway. This is like cleaning with vinegar, but more effective, without the smell or taste. Personally, I think distilled water is over-rated unless you have a high mineral content in your tap.

You mean like pipes that heal themselves by plugging leaks with sediment and lime? 8-)

Someone needs to have a talk with your local water treatment plant operator. There is a fine line between deposits and corrosion, but pH and hardness should be easy to balance.

I recommend you switch to Guinness.
For many of us, "Hard Water" is a fact of life -- like anybody near the Appalachians. The amount of, especially, limestone in the ground does do a nice job of filtering the water -- but it also forms stalagmites and stalactites (when the mites grow up, the tites grow down Smile)

I've always used tap water in assorted humidification devices and coffee makers, and, as you point out, the solution is always vinegar.

I'll have to talk to my brother, who is into home brewing - never thought about trying whatever he uses.
Or maybe my local brew-pub, which is only 2 blocks away!

And personally, I find Guinness a bit low on the hops -- I much prefer a nice IPA -- Aside from the fact that it has shot up to over $50 USD per case, I like John Courage!

And then of course, there is Single Malt!

Since the Star San is an acid base cleaner, although very dilute, it does fight mineral deposits. It's safe for use on the materials in your CPAP and harmless when diluted with beer water or whatever.

Guiness is no where near a favorite of mine, and I clearly underestimated you. Coffee

For beer purchases here in the Social Republic of PA where beer, wine and liquor are extremely regulated; I have developed a cash relationship with the regional wholesaler. As a result my costs per case are about 25% less than the distributor, and half of retail. My favorite trick is the motorcycle beer run. In this case, two cases and a keg.

I have the same question about using Star San to keep the humidifier sanitized.

This thread goes back a long way with a number of questions and responses. What is your specific question. It seems Sleeprider pretty well covered the safety and effectiveness in his original post. I'm a microbiologist with extensive experience with sanitizers. Star San appears to be a good choice if you feel you need something. I never use sanitizers since I never see any evidence of microbial growth. An occasional wash with dish washing detergent is all I use. But I don't doubt that some do have issues with microbial growth and additional sanitization may be necessary. Control III and peroxide are also good choices. In the case of all sanitizers, concentrated solutions are hazardous.

Anyone a sanitizers should read the material safety data sheet (MSDS) which can be found on line.

How did I miss this thread!!!

SleepRider, how close to Steubenville Ohio are you (my son lives there).

I too get a thin bio film and have been cleaning out on a regular basis.  Now to try my StarSan.

It would take maybe 1-hour and 15 minutes to reach Stubenville from here. Let's meet there sometime!

I use about 2-cc/quart of Star-San and it seems to work pretty good. I don't use it all the time, but a quick spray of the humidifier chamber prevents the biofilm and kills off mineral deposits.

I'll let you know the next time I'm in the area.

I'm curious about the aluminum plate on the bottom of the A10 humidifier... I'd be concerned over using an acid based sanitizer on that.
So far, baby shampoo has worked well... wife and I have had no respiratory infections.

Keep in mind that the sanitizer is commonly used on metal utensils. Are you sure the plate on the bottom of the humidifier is aluminum? I thought stamped stainless.
